Black smoke vehicle snapshot system of large truck with separated truck head and carriage

Abstract

The invention relates to a black smoke vehicle snapshot system of a large truck with a separated truck head and carriage. The black smoke vehicle snapshot system comprises a video data acquisition assembly; the video information acquisition assembly comprises a same-direction snapshot unit and an opposite-direction snapshot unit which are installed above a road, a side-direction snapshot unit installed on the side edge of the road, and a service processor which is in communication connection with the same-direction snapshot unit, the opposite-direction snapshot unit and the side-direction snapshot unit. The same-direction snapshot unit performs video acquisition on the tail part and the side surface of the vehicle, and the opposite-direction snapshot unit performs video acquisition on thefront part and the side surface of the vehicle; the side-direction snapshot unit performs video acquisition on a single side surface of the vehicle and a gap between a vehicle head and a carriage; andthe service processor processes the acquired video so as to compare the acquired video with a pre-stored database to obtain discharged smoke data. The black smoke vehicle snapshot system is low in false identification rate and high in detection precision; the system is high in environmental adaptability, is not interfered by environmental conditions, achieves the all-weather recognition and detection of the black smoke vehicle, and solves a problem that black smoke emitted from a long carriage cannot be recognized.

Description

technical field [0001] The invention relates to the field of exhaust gas monitoring, and more specifically relates to a black-smoky vehicle capture system for large trucks with separate front and compartment. Background technique [0002] The particulate matter emitted by smoky vehicles is a strong carcinogen, and the pollutants emitted by a large truck are equivalent to the emissions of 500 small cars, so it has become a key monitoring and prevention target. In recent years, more and more main traffic arterial roads in cities have been equipped with fixed smoky vehicle electronic capture systems and motor vehicle exhaust remote sensing monitoring systems. Departments are connected to the Internet in order to detect and restrict the passage of high-polluting vehicles in time to protect the health of the general public. [0003] Large trucks are mainly divided into two types: the first type is the integral type, which has a complete body, and there is an exhaust pipe at the ...
